TYPE-SETTING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 641,296, dated January16, 1900.

Application filed October 22, 1896. Serial No. 609,652. (No model.)

To [LZZ whom it may concern:

Be it known that we, LOUIS Kossurrr JOHN- SON and ABBOT AUGUSTUS Low,citizens of the United States, residing in the city of New York,(Brooklyn,) in the county of Kings and State of New York, have inventedcertain new and useful Improvements in Type-Setting Apparatus, of whichthe following is a specification sufficient to enable others skilled inthe art to which the invention appertains to make and use the same.

Our invention relates to the class of typesetter cases in which theremoval of the types by hand sets in motion'mechanism by which thesucceeding types are forwarded into position forremoval by hand. Onemethod of accomplishing this end is by the use of a trigger-lever,through the medium of which the advanced types lock the type forwardingmechanism, the withdrawal of the forwarded types causing saidtrigger-lever to release the clutch upon the power-shaft, so that thetypeforwarder is made to reciprocate as in our concurrent applicationfor patent, Serial No. 608,600, filed October 12, 1896.

During the withdrawal of the forwarded types by hand they arenecessarily drawn over the forward end of the trigger-lever, and as thelatter has to counteract the tendency of the clutch to rotate with thepower-shaft by reason of frictional contact therewith its forward endbears against the forwarded types with considerable force.

An important feature of our invention consists in providing the forwardend of the trigger-lever with a yielding type-bearing which, whileeffectually holding the forwarded type in position for removal, givesway to the types as they are withdrawn and returns automat ically intoits normal position after they have passed. By this means we reduce theresistance to be overcome by the fingers of the coinpositors whilewithdrawing the type to the minimum, rendering the device delicate andsensitive to the touch and avoiding undue wear or injury to the types.

Another feature of our present invent-ion relates to the means employedfor effecting the temporary depression of the forward end of the triggerlever before the advancing types, so as to avoid contact with theirfaces,

and consists in causing the type-forwarder to act directly upon thetrigger-lever to control the latter during the reciprocation of themechanism, substantially as hereinafter set forth.

Still another feature of our present invention consists in making thechannel-holder of skeleton form, thereby reducing its cost and weightwithout impairing its functions.

In the accompanying drawings, Figure 1 is a vertical longitudinalsectional elevation of the essential parts used in connection with asingle channel and holder, the parts being at rest in their normalpositions. Fig. 2 is a top View of the pusher, and Fig. 3 an endelevation thereof. Fig.4 is a front view of the front end of thetrigger-lever; Fig. 5, a side View thereof, showing the yielding bearingin section. Fig. 6 is a front elevation of the yielding bearingdetached. Fig. 7 is a sectional elevation showing the position of theparts immediately after the removal of the forwarded type. Figs. 8, 9,and 10 are elevations in detail of the channel-holder. Fig. 11 is asectional elevation showing the position of the parts at the completionof the forward stroke of the type-pusher. Fig.12 is a section upon planeof line 12 12, Fig. 7; Fig. 13, a sectional elevation showing theposition of the parts during the forward stroke of the type-pusher. Fig.14 is a front elevation of a series of channel-holders, (be.

O is the type-containing channel; H, the channel-holder; F, the frontguard, and B the supporting-bed. These parts are all like those shown inmy concurrent application hereinbefore referred to, except thechannelholderH, which, though essentially the same, is made skeletonform, as shown in Figs. 8, 9, and 10.

The type-pusher P is actuated through the pitmen g by the eccentric Q onthe powershaft S, the pawl B being controlled by the trigger-lever T, asheretofore.

The trigger-lever T behind its pivot t is formed with a cam-surface If,so situated that during the forward stroke of the pusher P it will beacted upon by the lifter 13 upon the extension 1) of the pusher P,thereby depressing the forward end of the trigger-lever, as shown inFigs. 11 and 13. When the parts are at rest and in their normalpositions, as shown in Fig. 1, the lifter 1) is free of contact with thelever T, so that the forward end of the latter rests against the underside of the forwarded type, as shown in Fig. 1.

The forward end of the triggeulever T is provided with a pivoted fingerM, a spring n tending constantly to hold the finger M upright in itsnormal position with its step n resting against the lever. During thewithdrawal of the types this finger M yields or gives Way sufficientlyto relieve them of undue strain or frictional contact, returningimmediately to its normal position after the types have passed.

What we claim as our invention, and desire to secure by Letters Patent,is

1. In a type-setter case substantially as described the combination ofthe type-channel holder and forwarding mechanism, a typeforwarder, atrigger-lever formed with an inclined surface and a lifter for engagingwith said inclined surface traveling parallel and suspended from thepusher substantially in the manner and for the purpose described.

2. The combination with the type-containing channel, channel-holder, andtype-forwarding mechanism substantially as described, of thetrigger-lever T, formed with the pivoted type-finger N, and spring 1?,and

stop n, whereby the type-finger is allowed to yield during thewithdrawal of the type and to spring back into its normal position afterthe types have been withdrawn, substantially in the manner and for thepurpose described.

3. The combination with a type-channel, channel-holder, andtype-forwarding mechanism, of the pusher P, formed with thedownwardly-projecting arm 19, having the lateral lifter 13, whereby saidlifter 19, has a parallel movement with the pusher P, and thetrigger-lever T, formed with the inclined surface If, the whole arrangedand operating substantially in the manner and for the purpose described.

4. The combination with a type-channel, channel-holder, andtype-forwarding mechanism consisting of the shouldered powershaft S,eccentric Q, eccentric-rods q, and the gravity-pawl R, of the pusher P,formed with the dependent lifter 19', moving parallel there with and thetrigger-lever T, provided with the yielding type-finger N, n, the Wholearranged and operating substantially in the manner and for the purposedescribed.
